NON-INTERFERING SIGNALING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 443,725, dated December 30,1890.

Application filed May 9, 1890. Serial No. 351,123. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. ONGLEY, a citizen of the United States, residing at New York city, in the county and State of New York, have invented a new and useful Improvement in Non-Interfering Signal Systems, (Case 11,) of which the following is a specification.

The invention relates to apparatus adapted for use in fire-alarm, fire-telegraph, hotel-annunciator, and other similar systems in which it is necessary to send distinct signals from several different points to a common receiving-station.

My object is to produce a simple and efficient apparatus for receiving said signals and for preventing mutilation of signals when two or more boxes are operated at about the same instant.

The invention consists in the improved receiver and in certain circuits and connections hereinafter described.

In the drawings, Figure 1 illustrates the receiver with the front plate and signal-disks removed. Fig. 2 is a diagrammatic view of an entire system. Fig. 3 is adetail of the circuit-controller used at the transmitter.

The receiver illustrated is provided with three disks or other surfaces, on which are placed in regular order numbers or other symbols by which the signal or information is indicated. The position of said disks is indicated in Fig. 1 by the dotted circles 1, 1, and 2. The disks are also shown in Fig. 2 in dotted lines, the disks in this case being behind the front plate of the receiver. In this plate are openings or windows 3, behind which the numbers on the disks are successively brought by the operation of a transmitter.

4 are knobs or handles on the outside of the front plate,'which can be grasped by the hand for the purpose of turning the disks in the direction of the arrows shown in Fig. 2. This motion puts under tension the propelling device or motor (indicated diagrammatically in Fig. 1) of the several disks. Each of these motors is provided with a detent 5 and a magnet 6 6 6", which when operated releases the detent and allows the wheel on which the detent-pin is placed to make one revolution. An entire revolution of this wheelmoves the signal-disk of the corresponding mechanism one space. hen the disk2 begins to move, the pin 7 carried thereby will move away from the handle of the two-way switch 8, allowing the spring to move the switch from the normal contact, as shown, onto the normally-open contact 9. This closes a signal-circuit at the spring 10. At the same time it cuts out the detent-magnets 0 (3.

At 11 is shown a second switch for automatically short-circuiting magnet 6 should the apparatus be accidentally left for some time without being reset by means of the handles 4. as above described. This short circuit is closed, when the pin 7 moves around, striking the arm of the switch and throwing it onto contact 12. At the same time the signal-circuit may be opened by the movement of the switch-arm 11 from its normal position.

13 is a handle, which, when moved to the position shown in Fig. 1, short-circuits all the detent-magnets of the receiver, and when moved toward the word On breaks these short circuits.

Referring now to Fig. 2, the transmitters will be described. \Vithin abox 14 is mounted any suitable motor 15 for propelling the transmitting mechanism when wound by means of the handle 16. Any suitable circuit-controller may be employed. I have shown break-wheels 17 17', having projecting teeth, which as the wheels revolve make contact with circuit-terminals 18 adjacent thereto. Fig. 3 indicates the fact that more than one circuit-breaking wheel and co-operating contact-spring is or may be employed. In the normal condition of the apparatus stop-arm 19 bears against the pin 20, and at the same time against a spring 21, which spring is in the following circuit: from the spring through magnet 22, wire 23 to battery, wire 24 to the frame of a succeeding transmitter, through the stop-arm 19 of said transmitter toacorrespondingspring21', magnet 22', wire 25 to the frame and stoparm.of the first transmitter. It is evident that any number of transmitters may be employed, each having a magnet 22 in the circuit of this one battery. The circuit just described is a local circuit extending between several adjacent transmitters, but not extending to the distant receiving-station. In the condition of the apparatus just described the armatures 26 would be attracted to the poles of the magnets and would be out of the path of movement of the stop-arms 19. At the transmitter on the right the handle has been moved to wind up the motor, and has thrown the stop-arm 19 away from its normal position. The first movement of the arm 19 carries its end above the armature before it breaks contact with spring 21'. As soon as it leaves said spring all the armatures 26 are elevated by means of their attracting-springs or otherwise. This position is shown in the drawings. The box first operated would be unaffected by this movement of the armature, having passed out of range and being free to complete its revolution. At the other boxthe box at theleft, for examplc the arm 19 is locked by the armature.

27 is a register or recorder preferably, though not necessarily a time-register, such as described in my application No. 337,424, filed January 20, 1890.

is a side view of a clock for controlling the position of two time indicating typewheels 29.

30 is a magnet in series with the detentmagnet of disk 1 of the receiver, and serves to move the type-wheel 81 step by step at each make and break in the circuit. is a. similar magnet for moving the type-wheel 33, and is in series with the detent-magnet of disk 1 of the receiver.

Si is a printing-magnet in the register and is in series with the dctent-magnet 2 of the receiver.

A single battery 35 serves to energize all of the magnets of the receiving apparatus ex ceptbell 36, which is shown in circuit with a local battery.

The operation of the system will now be described. It is supposed that the switch-arm 13 is moved to the rightand the several disks have been set at zero, (windingtheir motors,) whereby the receiver is put in operative c011- dition. At the transmitter on the right the arm 10 is moved suflicicntly far to wind the motor to such an extent as to cause the circuit-controlling wheels 17 17' to revolve twice. The first effect is to operate the non-interference mechanism, as alreadydescribed. hen the handle is liberated and the transmitter allowed to run down, the wheels 17 17 turn together in the direction of the hands of a watch. The live teeth on wheel 17-first make and break contact with spring 18 in the following circuit: spring 18, wire 37, wire 38 to switch 8, wire 39, detent-magnet (3, wire 39, wire 38 to magnet 30 of the register to the battery back to the frame of the transmitter and the circnit-controlling wheel, thus energizing and de-energizing the detentnnagnet five times and bringing the numeral 5 before the window, as shown in Fig. 2. The next effect is after a short interval for the single .ooth on wheel 17 to make and break contact with its contact-spring, which is in the following circuit: spring, wire 40, wire 4], switch 8, wire 42, detent-magnet 6, wire l2, wire -l1 to magnet 32 of the register to the battery and back to the transmitter. This sets disk 1 with the numeral 1 before its window. Thus it will be seen that the single receiver shows at a glance the number of the box operated, and the type-wheels of the register are set to indicate the same information. As the transmitter continues to move, the pin 20 makes a contact with spring 43, which is in the following circuit: spring, wire l i, detent-magnet 6", wire 44. to print ing-magnet 34- of the register or recorder to battery and back to the transmitter. This circuit is closed once for each revolution of disks 17 17. As shown in Fig. 2, the transmitter at the right has revolved twice, closing the last-mentioned circuit twice, bringing the numeral 2 before the window of disk 2. As has already been stated, as soon as disk 2 begins to move the detcnt-magnets of the other disks are cut out by switch 8. The object of this is to prevent further motion of disks 1 1 during the second or succeeding revolutions of the transmitter, as it is desired that they should remain as set by the first revolution to indicate the number of the station signaling.

It will he understood that the numbers on disk 2 indicate any desired information according to a predetermined code. For example, if the apparatus is to be used in a fire-alarm and extinguishing system, 1 may indicate that the thermostats have operated, 2 may indicate that water has been admitted to the automatic sprinklers, fee. If used in ah'otel-annunciator system, 1 may indicate messenger, 2" water, 3" writing materials, the.

Instead of numbers indicating certain information or wants the information may be placed directly on the disk. In a hotel, for example, having more than ninety-nine rooms it would be necessary to employ more than two disks for indicating the higher numbers, and in that case an extra wire or wires would have to be used between the receivers and transmitters and additional circuit-controlling wheels and springs would be necessary, as is evident. At each movement of disk 2 the printing-magnet 31- of the receiver is energized, bringing the platen against the paper and printing the box number and time, if a time-register is employed. If, therefore, the strip shows the box or room number twice, the information indicated by 2 is recorded, and so on for other numbers.

During the night, or when the operator is to be away from the receiving-station for a considerable time, the switch 13 is moved to the position shown in Fig. 1. In this condition of the system a signal sent from a transmitter would not affect the disk of the apparatus, but would be recorded in the register 27. Should the receiver be left with handle 13 to the right, the disk 2 would continue to move at each make and break of its circuit until pin 7 should approach the limit of a complete revolution, when said pin would move switch 11 onto its contact and thus antomatically short-circuit magnet 6". The bell 36 may be placed at any desired position and several bells may be placed in the same circuitfor example, in a fire-alarm system for a factory, one bell may be placed in the oliice, one bell in the engine-room, one in the superintendents room, &c.

The details of the short-circuiting switch, the detent mechanism and signal-carrying devices of the receiver, and the circuit-controlling apparatus of the transmitter may be varied to a considerable extent without departing from my invention, and I do not wish to limit myself to the exact apparatus shown and described.

Having thus described my invention, what I claim is 1. The combination of signal-disks, independent detent-magnets in separate circuits controlled by means of a suitable transmitter, whereby the box or station number may be indicated, and an additional disk, also controlled by the transmitter and a separate circuit and indicating the number of revolutions of the transmitter, substantially as described.

2. The combination of signal-disks independently controlled by means of a suitable transmitter, whereby the box or station number maybe indicated, an additional disk, also controlled by the transmitter and separate electrical mechanism and indicating the number of revolutions of the transmitter, and a short-circuiting device for the first-named signal-disk mechanism, substantially as described.

3. The combination, in a signal-receiver, of signal disks and motors for moving the same, a detent for each motor, a magnet for operating each detent in a line extending to the signal-transmitters, a circuit-controller at the transmitters for each line, and a switch moved onto short-circuit contacts by the signal mechanism when approaching the limit of its motion, substantially as described.

4. The combination, with a transmitter and a receiver comprising a signal disk or disks for indicating the box-number and a disk for indicating the number of revolutions of the transmitter,with detents and motors therefor, of a recorder having a type-wheel-propelling magnet in circuit with each detentmagnet of the first-mentioned disks, and a printing-magnet in circuit with the detentmagnet of the latter disk, substantially as de scribed.

5. The combination, with a transmitter and the receiver comprising a signal disk or disks for indicating the box-number and a disk controlled by separate electrical mechanism for indicating the number of revolutions of the transmitter,with motors and detents therefor, and shunts for the box-number mechanism, of a recorder in circuit with said receiver, substantially as described.
